5 lo-cost ways to go green at home  

1. "if just 10 homeowners replaced their older appliances with EnergyStar®-qualified ones, it would be equivalent to planting 1.7 million new acres of trees."
2. "Turning down the thermostat in cold weather and inching it up during the warm months can save as much as 3-5 percent for each degree adjustment. In fact, as much as 60 percent of your energy bill may be heating and cooling related. Get some new clothes for your hot water heater by placing an insulating jacket around it (usually costs under $20) and outfit your pipes for even less.
HVAC (heating, ventilation and cooling) changes can contribute even more – something as simple as cleaning your furnace’s air filter monthly during heavy usage times can make a big difference.
Shade your east and west facing windows to prevent the most brutal heat intrusion during summer months. And if your house doesn’t already possess dual-pane energy-efficient windows, why not start replacing those windows slowly, but start with those that receive the most intense sun exposure first?
Saving heat generating activities such as dishwashers and cooking until the evening hours can help you ease up on cooling costs as well as your local energy grid.
Using ceiling fans to move air on low speeds (even if TV reality remodeling shows think they’re not fashionable) can permit you to push the thermostat in either direction, providing more circulation of either cool or warm air."
3. "You may love the forceful flow of water at your faucets, toilets and showerheads, but did you know that installing aerators on them could cut your annual water consumption by more than half?
And then there is the commode... Toilets installed 15 years ago use more than twice the amount of water than the newer low-flow models. Even if you have older toilets, however, you can adjust your float valves to permit a lower water flow into the tank."
4. "...if every person who received the newspaper switched one light bulb to a compact fluorescent light (CFL) bulb, it would be the equivalent of taking 89,000 cars off the road."
5. "The U.S. Department of Energy says that adding insulation to the attic is relatively easy and very cost effective. To find out if you have enough attic insulation, measure the thickness of the insulation. If it is less than R-22 (7 inches of fiber glass or rock wool or 6 inches of cellulose), you could probably benefit by adding more. Most U.S. homes should have between R-22 and R-49 insulation in the attic." The article says an energy audit can cost $159 to $359 but that you can recoup that in about a year from your savings.

These are some interesing things to do. I've started buying the lightbulbs, and we always turn up or down our thermostat. We have a newer model fridge, so that should be okay. Makes me want to go out and buy a new toilet! LOL
